London: Pop sensation Lady Gaga, who is known for her bizarre sartorial style, sported a dress made of purple hair.

The 25-year-old singer, who began her Born This Way Ball world tour in Hong Kong, teamed up the outfit with white platform boots, white gloves and a white hat, reported a website.

The pop star's most controversial dress was made of raw beef, which she wore for the 2010 MTV Video Music Awards. Gaga's tour began the previous night in South Korea and only those who are 18 or older can attend the events.

The 'Bad Romance' singer will perform 110 shows worldwide. She will perform in Hong Kong on May 2 and in Tokyo and Singapore on May 10 and May 28 respectively.
